Persistence of Bacillus thuringiensis Berliner insecticidal activity on cotton foliage
Environmental Entomology 10 (3), 400-401
Abstract: The persistence of insecticidal activity of Bacillus thuringiensis Berliner (variety kurstaki, HD-1 strain) on cotton leaves in the field was determined in 1976 and 1977 by using two techniques and two insect species. In both years the insecticidal activity half-life was between 1.5 and 2 days.
